''Twas the night before the SOLMAR!

[Miller Mod Saws]

Now for porting. I'd like to say based off what I know of the 7900 but that's not true I just pulled a starting point out of my butt. Lol. If that dosnt work. Well we will try another cylinder I got spares here I layer out the gasket to gasket match. And I marked the cylinder walls were I'm going to cut out to open up these lower transfers and the tunnels will get a little work while I'm here.

Wow Carl, you've got a lot done!

Looking good so far! This is a truly custom saw!

I didn't want ordinary for this build. I just hope it's a good runner when done. It didn't run to awful shabby stockish. Not being able to widen the exhaust worries me a little but we will see.

Here's a shot of the roughed in transfers.

Now for my numbers well we will see if they work. For the numbers I'm gonna give the intake is based off looking where it closes. But the trans and exhaust ibset with a ring. But remember it has a dome piston in it so the heights will actually be a bit higher than the number I give.

105/125mains-129secondaries/78 is the numbers I choose to start with.

 

[Miller Mod Saws]

I could not widen the exhaust do to the ring ends being so close. But here's my exhaust at 105. Notice my little whoops below the exhaust. I really hate when I do stupid stunts like that. Luckily it will not affect anything. As I just nicked the nickasil and it's way below the rings.

 

[Miller Mod Saws]

On the transfer. When I pushed the ring up in there the rings started opening about 131 and blow down got greater towards the exhaust. I changed that up. I raised the mains to 125. But only raised the secondaries a couple degrees to 129. No widening.

 

[Miller Mod Saws]

And finally the intake. I widened this bad boy and lowered it to 78

Very nice. Liking where this is going. Can't wait to see how it ends up.

Hopefully I get time tomorrow the muffler needs a little clearance work and the jug needs a hair cut before I reassemble. And see if it's brings a smile or a frown.

Great work Carl. Fascinating stuff.

Domed Pistons are a place where the Torquesoft measurement vs. Degree software may come in handy. It actually works.

Carl, where does the piston crown end at BDC at the exhaust port floor? Looks like you've got a mile of skirt left at TDC. Just wondering if this a design where you could drop the floor for more time/area being you cannot widen.

Your work looks great, as usual.

At bdc the piston just barley sticks up above the floor. I will try and take a pic when I reassemble. And at TDC I don't hav as much now because I lathed off 2mm of that but there's still plenty. Lol

Cool idea using the 665 jug Carl.

You probly got a few layin around

 

[Mastermind]

I have a few too. Does anyone need one?
